Product Details
The Thermo King O-Ring Water Pump 331646 is an OEM-specified sealing component for water pump assemblies used in Thermo King transport refrigeration applications. This part functions as the primary sealing element between pump components to prevent coolant and fluid migration. Service technicians replace this O-ring during scheduled pump maintenance or when inspecting for leaks to restore system integrity and uptime. Exact material composition and dimensions conform to Thermo King internal specifications and match original equipment tolerances.
Efficiency & Sustainability
This O-ring supports efficient, fuel-conscious cooling by preserving coolant integrity and preventing leaks that reduce thermal performance. Proper sealing preserves temperature control in reefers and refrigerated trucks, contributing to lower compressor workload and more consistent fuel-efficient cooling. Compatible service practices align with Smart Reefer SR-4 controls and CARB Evergreen initiatives when integrated into compliant Thermo King systems.
Installation & Maintenance Tips
Inspect the pump housing and sealing surfaces for damage before installing the O-ring.
